It is vitally important that the integrity of your Flue Gas Probe is maintained in order to ensure continued accurate results on your Flue Gas Analyser.

This is something a lot of service and calibration houses neglect but we don't at BlueLine® Instruments. That's why we always ask you to return both instrument and probe when its time for your annual service

Complete Range of Accessories.

A multi sensor and function packed flue gas analyser for medium and larger sized Oil, Gas and Pellet Heating Systems with an additional pressure measurement channel for Differential pressure measurement.

The MultiLyzer STe has aswitchablehigh range CO sensor  ( 0-20,000ppm) making it ideal for the maintenance of Solid Fuel Heating Systems with temporary CO peaks of up to 20,000ppm or bivalent modulating Combined Heat & Power (CHP) plants.

It can also incorporate optionalNO, NO2, and SO2 sensors and can be fitted with a direct reading CO2 sensor for measuring directly in voids etc. These can be retro fitted at any time at our works. The MultiLyzer also utilises a 5 year O2 sensor to keep servicing costs low.

Three 'K' Type temperature connection points and a separate temperature measurement function on the instrument menu give multiple temperature reading options for use with Clamp Probes and other temperature accessories as well as the standard flue gas and ambient temperature readings.


A separate Pressure Loss menu llows Let By and Tightness testing and a separate Pitot Tube measurement option is also available..

A unique filtration system in the sampling probe line ensures that your instrument stays dry at all times.

This, coupled with an optional 5 Year Fixed Price Service Contract, makes the MultiLyzer instrument a very cost effective flue gas analyser when working across multiple fuel disciplines.
